Comparison of graphite nanoplatelet (GNP) and carbon black (CB) pastes as thermal interface materials shows that the optimum filler content for attaining the maximum thermal contact conductance (copper proximate surfaces, roughness 15 μm) are 2.4, 15 and 2.4 vol.% for GNP, CB (Tokai) and CB (Cabot), respectively.
We report the configuration in which the thermal conductance is maximum.
Objective measurements revealed that there was significantly higher liquid moisture management capacity, water vapor permeability, thermal conductance and maximum value of heat flux in the Reusable than in PROTEC briefs.
It is shown that for both of these geometries, the proposed method estimates the thermal conductance with a maximum discrepancy of 10% with respect to the experimental results, compared to the 42% usually obtained with more conventional models.
There are optimum allocations of the number of thermocouples and optimum allocations of thermal conductance of heat exchangers corresponding to the maximum cooling capacity and the maximum COP, respectively.
Results showed that the overall thermal conductance of the bed and the maximum practical specific cooling capacity increased when reducing in flat tube thickness and fin pitch as well as by increasing in fin thickness and water channel wall thickness.
The thermal conductivity also has been determined, by parallel thermal conductance, from 5 to 300 K.
The analysis results show that the maximum coefficient of performance (COP) and the maximum cooling capacity of the TEC system can be obtained when the finite total thermal conductance is optimally allocated.
Thermal conductivity from 50 K to 300 K was determined using the parallel thermal conductance method.
The electronic thermal conductance (κ e ) also exhibits eight peaks, and we noticed that the local maxima of the κ e curve nearly coincide with the local minima of the G e curve.
